MarCum Technologies introduces the Lithium L-series flashers with a great rebate to boot.

New Hope, MN – From MarCum Technologies, the industry champion in ice electronics that serve the angler first, comes a new riff on established innovations.  MarCum’s engineering feats have led the sonar space for decades, with a healthy list of patents to prove it.  From Interference Rejection (IR) to moveable zoom, our advancements are translated to more fish on ice.  A recent improvement comes in the form of a  patented “light pipe” – a brushless system that provides razor-thin target returns that give anglers the ultimate in resolution and fish-catching clarity. 

For the last 20 years, it’s technology like this that MarCum has pioneered and baked into every system we make.  This year, that technology extends beyond the electronics and moves to what powers it.  MarCum has always followed the highest standards in applying the best materials and methods available, constantly striving to improve our products knowing you get out, exactly what we put in to every sonar and camera built. 

With Lithium battery technology entering our daily lives, and the ice industry, in bold fashion we recognize that it’s a superior fuel source and should be properly paired to the most advanced sonar on the market.  Lithium drives our ice augers and even our cars, such that when it comes to our ice electronics, without putting it in, we’d be leaving something out.  That’s why even though the improvement may not be to the guts of the machine, the end result is MarCum through and through. 

The MarCum M3L and M5L focus on taking existing advancement to the next level, finally with a power source worthy of the technology it fuels.  The M3L offers the same IR, moveable zoom, light pipe, and target separation MarCum fans have come to love from the existing M3, now studded with the 12V10AH LiFeP04 powerhouse and charger in the MarCum Brute.  Similarly, the M5L features this same tech but with a switchable transducer, and even more distinct clarity through the Super Fine Line Feature.  It too sports a MarCum Brute and charger, the new standard in LiFeP04 technology and safety. 

The addition of the 12V10AH Lithium LiFePO4 MarCum Brute will shave pounds and increase runtime of each system.  MarCum’s Product Development Engineer, Rocky Holmes says “We’re constantly looking at ways we can make a Marcum customer more comfortable so they can spend more of their energy fishing than fiddling.”  That means lighter and easier to hole-hop, but also more convenient to own.

Comfort comes in weight savings, but also in the fact that MarCum isn’t increasing the price of their industry-leading, time-tested sonar to do it.  The $100 Lithium LiFePO4 battery exists as a value-add to customers looking for the best electronics on ice, but we’re sweetening the pot even more.  Now until the end of the year, you get the best flashers ever made in the M3L and M5L, at a substantial discount from previous models, and a $50 rebate to boot.

Fish lighter this season, but not in the pocketbook- with MarCum Technologies.  For more information on the M3L and M5L by Marcum, go to
